# zkCross Network

Permissionless DeFi and AI infrastructure for Web3.

zkCross Network is the execution infrastructure layer built to move value safely across blockchains. It gives ecosystems, developers and AI-driven applications a way to access liquidity, route actions, enforce risk boundaries and settle across chains without relying on fragile third-party execution rails.

At its core, zkCross was built to solve a structural problem in DeFi. Chains are fragmented. Liquidity is fragmented. Execution is often stitched together through external bridges, aggregators, custody layers and signing dependencies that introduce trust assumptions and operational risk. Automation systems can suggest actions, but most cannot enforce hard boundaries at the protocol layer.

zkCross exists to fix that.

Instead of building another surface-level DeFi app, zkCross built the underlying execution stack. That stack combines cross-chain routing, deterministic control, secure signing, settlement verification and continuous monitoring into one reusable infrastructure layer.

This is what makes zkCross different. It is not a wrapper around someone else’s rails. It owns the rails.

### What zkCross enables

zkCross gives ecosystems and applications a production-ready infrastructure layer for:

* Cross-chain routing and settlement
* Liquidity abstraction across EVM and non-EVM environments
* Deterministic enforcement of execution rules
* Permissioned signing and authorisation
* Non-custodial vault-based execution models
* AI-ready execution rails for automated systems

For users, this means simpler access to multi-chain liquidity and execution.

For ecosystems, it means they can activate DeFi functionality, cross-chain movement and automation without rebuilding core infrastructure from scratch.

For AI-driven products, it means automation can run inside enforceable boundaries rather than relying on trust in off-chain logic or human discretion.

zkCross is the infrastructure foundation. Products such as Surf are consumer-facing deployments built on top of that foundation.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://zkcross-network-1.gitbook.io/learn.zkcross.network/welcome/zkcross-network.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
